Other Parts Discussed in Thread: BQ79616
Hi,
I'm using ferrite beads as advised on datasheet of Bq76pl455A-Q1. I would like to ask that which location(1. or 2.) is better for ferrite beads?
1. Option(Between cell input and balancing FET): In the 1st option, Cell voltage can be read incorrectly when there is balancing current on ferrite bead. Because the balancing current creates a voltage drop on ferrite bead.
2. Option(Betwen balancing FET and filter resistor): In the 2nd option, the balancing current has no effect on ferrite bead.
Sorry for the bad image as below. Hopefully ferrite bead positions (1) and (2) are understandable.
Thank you.
